Many people are concerned about what items to add to a physical exam to check the thyroid, and is the more expensive the better? How to read the thyroid test report? Does the detection of thyroid nodules mean that there is a possibility of cancer? How to choose the test for thyroid nodules? Is the more expensive the better? This is not true. Compared with other organs, the thyroid gland is a superficial and substantial organ, and its anatomy and physiological structure determines that thyroid diagnosis is different from that of other organs. Ultrasound diagnosis is the most realistic and feasible method for diagnosing thyroid nodules in China. Other more expensive tests such as CT, MRI and even PET/CT are not the preferred diagnostic tools. How can I read a thyroid ultrasound report? This is something very specialized, but you can initially distinguish benign and malignant lesions by some key words. If the ultrasound shows a hypoechoic solid nodule, irregular shape, unclear border, abundant blood flow in the nodule and tiny calcifications, then malignancy is more likely, and vice versa, benign is likely. Will all thyroid nodules become malignant? The majority of thyroid nodules are not cancerous, but only a very small number of tumors are precancerous and eventually become malignant. For some patients whose diagnosis is unclear, thyroid puncture is needed to clarify the diagnosis. Therefore, don’t panic if you find thyroid nodules, but go to the hospital for examination as soon as possible. What kind of thyroid nodules should be prevented from turning into cancer? The following conditions should be taken into consideration: mixed nodules of substantial and cystic nature; nodules with rapid enlargement (at least 20% increase in both length and diameter within 1.5 years); hard texture and low mobility; nodules with symptoms such as compression of trachea, esophagus, nerves and blood vessels; nodules with unclear borders, rich blood flow and calcification on ultrasonography; enlarged lymph nodes in the neck; history of radiation exposure to the neck; and thyroid cancer in the family. family history of thyroid cancer, etc. For suspicious nodules, ultrasound examination should be done every three months. If the nodules increase significantly or show suspicious malignant signs, they should undergo puncture examination or be terminated for observation and direct surgery.
